An Improved Method of Building Rapid 3D Modeling Based on Digital Photogrammetric Technique
Building 3D modeling is a fundamental but expensive works to digital city engineer. For cutting off the workload of that, an improved rapid modeling method based on digital photogrammetric technique is proposed. Two main issues are resolved in the method. The first is how to trace and recognize the roof surfaces of a building according to its profile lines, and the second is how to create right solid models for complicated buildings usually with multiple parts. The paper gives a detailed description about the solutions and involved algorithms. Finally, multiple buildings with different roof styles are selected to test the improved method. Results show that it can get right 3D models for common buildings, and reduce the workload of delineating roof lines and possible model mistakes.
